MMKV is an efficient, small mobile key-value storage framework developed by WeChat. react-native-mmkv is a library that allows you to easily use MMKV inside your React Native applications. It provides fast and direct bindings to the native C++ library which are accessible through a simple JS API. Get and set strings, booleans and numbers. Fully synchronous calls, no async/await, no Promises, no Bridge. Encryption support (secure storage). Multiple instances support (separate user-data with global data). Customize storage location. High performance because everything is written in C++. ~30x faster than AsyncStorage. Uses JSI instead of the "old" Bridge. iOS, Android and Web support. Easy to use React Hooks API. StorageBenchmark compares popular storage libraries against each other by reading a value from storage for 1000 times.
